1. An extreme love for something; this exclamation is often made after ejaculation, but the tip of the penis burns as well.

2. A strong word for something you want to fuck, without saying you want to fuck it.

3. You just want to fuck the bitch.

A girl walks into a bar and you tell your friend beside you "gütengee!" He also knows what "gütengee" means. So he glances to see if she's fuck worthy and tells you to proceed, or lets you know you're to drunk and she's a fat bitch, or a gatekeeper.
